There's a tech article on this site on how to do it. If you want, you can bring it to my dad's shop in Orange County and he'll do it. He converted his 92 RS from TBI to TPI last year. He knows how to do it using the stock TBI wire harness.

Hi,

Thats not a bad deal either. Jim (www.jimsperformance.com) does the harness conversion as well.
